PTC SYSTEM
OVERVIEW AND OPERATION PROCESS
1. OVERVIEW
The supplementary electrical heater is installed in D27DT engine equipped vehicle as a basic
equipment. The PTC system is operated by the measured temperature values at the coolant
temperature sensor and the HFM sensor. This device improves the heating effect by increasing
the temperature of flowing air into the passengers room. This system needs higher electric
power than conventional system due to it heats the ceramic in PTC with the electricity. And, the
alternator capacity has been largely increased (12 V ~ 75 A / 90 A to 12 V ~ 140 A). Non-
operational Condition
- During engine cranking
- Too low battery voltage (below 11 V)
- During preheating process of glow plugs
